IMPROVEMENT IN ROOFING.

The Schedule xexerred to in these Letters Patent and making part of the same ing tin-ming part of this specification.

Figure 1 represents a transverse section ot my improved joint for roofing.

Figure 2 is a side view of the same.

Figure 3 is a plan view of the same, showing the joint and water-channel.

Figure 4 is a transverse section through the waterchannei, taken on the line :v m, iig. 3.

Figure 5 is alongitudiual section of the same, takenon the line y y, iig. 3.

Figure 6 is a plan or top view ot' four united sheets, showingthe general arrangement of water-courses.

parts.

IThis invention relates to a new jointfor connecting metal roofing-plates, and to a novel arrangement of providing water-courses with transverse projecting joints; and has for its object to combine great strength with simplicity ofcoustruction, so that the joints will be durable and comparatively inexpensive, while a' free escape of water is provided at the end of each joint, so that the water cannot accumulate on any part of the root'.

This invention relates to improvements in metal rcoting;` and consists in so joining the sheets composing the roon g that the joints shall be eXpans/ible, and

water-channels or troughs be formed at their angles, as

hereinafter set forth;

A and B in the drawing are two adjoining sheetl metal rooting-plates. Their adjoining edges are turn' This forms Vin itself a Similar letters of reference indicate corresponding' The two flanges a b are riveted together by means of rivets c c, and between them is placed a piece, l1, of water-proof fabric. This fabric isby the rivets, firmly clamped, and prevents every particle of water from passing through the joint.

This joint will form a ridge, projecting above the roof', and permits full expansion and contraction ot the metal plates. Joints are thus made projecting at thefonr edges of each roofing-plate, so ,that they are formed on the root` `in longitudinal and transverse courses.

Water-passages are formed at each corner of each plate, as is clearly shown in iig. 6.

Each of these passages is formed by bending the metal down into a semi-cylindrical' trough, e, at the corner, and the two troughs, which come together ou ltwo adjoining plates, are made to overlap each other,

and riveted together, as is clearly shown in g.`3, 4,

The boundary of each trough c is defined by a slightly upward-bent portion, f, of the metal, which gives elasticity tov the joint, allowing free expansion and contraction of the metal.

The four troughs, formed at the four corners of each' plate, project all in different directions, so that a free discharge of water in each direction is provided.

Tile waterwill, with such free channels for escape,l not be apt to overflow the joints, and the water-proof qnality of the roof is consequently increased.

Having thus described my invention,

I claim as new, and desire to secure by Lett-ers Patentj 1. The plates A` and B, so constructed and arranged as to form the water-troughsee at' their corners or angles, substantially as specified.

2. A rooting-plate, formed by the sheets A and B, united by the self-supporting lap-joints a c, as set forth, whereby the same are permitted to expandin the manner described.A
